Specification of Letters Patent. Patented 11116 11, 1918 Applicationfiled February 1, 1917. Serial N 0. 145,858.

To all whom it may concern:

Be it known that 1, JOHN ARTHUR FERRIs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Fence-Gates, of whichthefollowing is a pecification.

This invention relates to improvements in gates, especially for farmservice, of which the following is a complete description, referencebeing'had to the'accompanying drawings making which Figure 1 is a sideview, showing the gate raised in dotted lines.

Fig. 2 is a to plan view.

Fig. 3 is a sit e view of the cam disk.

Fig. 4 is a vertical section through said. disk.

Fig. 5 is a detail sectional view of the lever clamp.

F1g. 6 1s a slde view of one of the cam plates.

Fig. 7 is a detail sectional view through one of the connections betweenthe bars and the battens.

Fig. 8 is an outer side view of the hand lever clamp showing its lever 0held in place by a guard bar X.

Fig. 9 is a plan of the catch spring for the hand lever clamp.

Similar letters of reference refer to similar parts throughout theseveral views.

As the gate is particularly intended for farm service, the frame ispreferably made of wood, and comprises a number of vertical battens, o,a), 4L, 4:, that support and are pivoted to horizontal bars 0, by bolts6, passing through the said members, at their intersections.

At each intersecting joint of the vertical battens with the horizontalbars 0, are inserted in the bolt holes of said horizontal bars, flangedmetal ferrules Z, to prevent friction in wet weather. Pivot bolts 6 passthrough said ferrules Z and bolt holes and pivot said joints as shown inFig. 1.

The gate braces, d, are pivoted to the rear end of the gate at the topthrough the vertical battens '0, and top horizontal bar, and reach downdiagonally on each side of said gate, spanning the horizontal bars 0,and are loosely inserted into a lever clamp, and can be firmly clampedto the adjacent vertipart of this specification, in

cal battens by movement hereafter described, and as shown inFig. 8, andby the dotted lines in Fig. 1.

The hand clamp of the gateconsists of a cam disk k, providedwith a handlever 0,

said cam disk being formed with several seihispherical bosses i, on eachside of the dis In close proximity to said disk A" are cam plates it, itthat are formed with a series of circular inclined grooves 1", as shownin Fig. 6, adapted to receive the semispherical bosses 2', of the camdisk is, said bosses to travel from the lower to the higher plane in thecircular inclined grooves 1", when being clamped. By such action therelative distance between the cam plates h and the said clamp plate j isreduced, as clamp plate j is connected to the cam plate It by bolts 92as shown in Fig. 5, so that the diagonal braces (Z, are firmly clampedto the adjacent vertical battens u, and the horizontal bar connectedtherewith, as shown by the dotted lines representing said lever in Fig.1 and the gate is thereby rigidly held parallel to the roadway or at anydesired angle.

The hand lever 0, is held locked in its lowest position by a catchspring X, and the said lever 0 is freed from the catch spring X, bypressing back the free end of the catch spring.

The gate lock lever 10, is pivoted to one of the lower horizontal barsof the gate, and at the lower end of said lever is pivoted a wheel p,that slightly rolls upon the roadway toward the rear end when the leverclamp is unlocked and the rear end of the gate is raised, therebypreventing the front end of the gate from dragging on the roadway.

The lock lever to which said wheel is attached is in the position to thelock gate slats S S to be locked to post a, or unlocked, as may bedesired by a back and forth sway of the lever and when locked the freeend of the gate rests upon said wheel, as shown in Fig. 1.

The gate post 5, in conjunction with the vertical battens o are providedwith vertically extended hinges 3 that are of a length that the gate canbe lifted up, a distance sufficient to allow small stock (as sheep andhogs) to pass through, and to swing clear over deep snow.

of said lever 0, as
